5 Verification and Calibration

Verification Procedure

Introduction

Verification is recommended to verify that the instrument is working properly during incoming
inspection - as an acceptance test. Verification is also recommended if you notice suspicious
instrument behavior or if there is a question about the performance of the instrument. Verification
procedures can be time consuming as they verify the operation of a single channel at a time.
Performing a reference calibration and a channel calibration provides the same high
level of confidence as the manual channel-by-channel verification process.
Verification is not necessary as part of a standard maintenance cycle. It is also not necessary after
performing any of the calibration procedures, as the calibration processes verify that the reference
and channels are functioning within specification.
Verification commands set each channel to a specific output level, which can then be used to verify the
specified accuracy of the channel at that operating point. If the instrument fails any of the verification
tests, try performing the Reference and Channel calibrations again. If verification is still unsuccessful,
return the unit to a Keysight Technologies Service Center.

Verification Fixtures

A multi-channel breakout board assembly can simplify verification when planning to verify all
channels. This can be constructed by wiring all BT2152A/B channels in parallel at the breakout board.
Only one channel at a time can be tested with this arrangement. When selected, that channel is
electrically connected. The remaining channels have internal switches keeping them disconnected
